Subject: AUDIT: Fix user pointer deref thinko in sys_socketcall().
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4bcff1b37e7c3aed914d1ce5b45994adc7dbf455;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

AUDIT: Fix user pointer deref thinko in sys_socketcall().

I cunningly put the audit call immediately after the
copy_from_user().... but used the _userspace_ copy of the args still.
Let's not do that.
